VAPOR-BURNER.

i SPECLFICATION forming part of Letters Patent No. 287,911, datedNovember 6, 1883.

Application filed April 3D, 1883. (No model.)

Ohio, have invented .certain new and useful Improvements inapor-Burners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as vwill enable othersskilled inthe art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspecifica-tion.

lMy invention relates to an improvement in vapor-stoves; and itconsists- First, in the'combination of the tank or retervoir, a pipeconnected thereto, and a horizontal pipe secured rigidly to thereservoirpipe, and which horizontal pipe has the burnv ers connectedthereto, and a mechanism for extinguishing the burners when the pipesare moved onpartially rotated. The object of this partof my invention istornake the reservoir removable and to connectf it with the burners,l sothat Whenever the reservoir is moved for the purpose of beingV filledthe burners are automatically extinguished, so asy to preventexplosions.

The second part of my invention consists in` providing the horizontalpipe to which the burners are attached with suitable bearings in theframe of the stove and connecting this pipe rigidly to the pipe whichleads down from the reservoir, so that When the reservoir is moved thepipe having the burners attached thereto will partially rotate or moveat the same time. The object of this part of my invention is to rigidlyconnect the pipe which leads downward from the reservoirto thehorizontal pipe to `which the burners are attached in such a manner thatthe two shall move together, and thus dispense-With any coupling orpacked joint between the two parts.

rEhe third part of my invention consists in ashut-off or pivotedplatewhich canbe moved so as to intercept the vapor and prevent it frompassing into the burner, and which plate has a groove, depression, orcut-away part upon one side, Vso that the vapor can pass through thiscut-away part. The object` of this part of my invention is to provide acutod or pivoted plate Which can be made to intercept the vapor andprevent its passage intoV the burner to form an auxiliary heating jet orllame, and which flame is projected against the top of the stand-pipefor the purpose of maintaining the heat or vaporization in the parts ofthe burner, so as to keep it for instant use, and lto form a'heating-jetwhen the main lanie is not burning. I

Another part of my invention consists in a y trap or sediment-collector,which will be more fully described hereinafter.

Figure lis an end view of myinvention. Fig. 2 is a plan view of one endof the stove. Fig. 3 is a side elevation. Figs. 4, 5, 6, and 8 aredetail vieWsof the burner. Fig. 7 vis a Vertr cal section of the trap.Figs. 9, 10, and l1 are modications of the mechanism shown forautomatically extinguishing the burners.

A represents an ordinary vaporstove of any desired shape, size, orconstruction that may be preferred.

Thetanlr or reservoir B is intended to be filled only after it has beenturned from a vertical into a horizontal position, as shown in Fig. 1,and is therefore provided with a small funnel or other similar device,C, as shown.

The pipe D, upon which this reservoir is placed,

mayeither be bent in the form here shown or any other that may bepreferred, and in order to regulate the distance it shall move there isavguide, E, secured to one end of the stove, as shown in Fig. 2. Thisguide is asimple keeper or band of any suitable shape or description,which holds the pipe D in contact with the end ofthe stove, and whichforms a stop at each end for the pipe, to prevent it from bei ng movedtoo far. After the tank has been filled, and th en adjusted intoavertical position., it is held in place by means of a small set-screw,spring, catch, or any other suitable device, F, which may be preferredforthat purpose. The lower end of this pipe D terminates in or isconnected to the trap G, for the purpose of catching any Water,sediment, or other impurities which may be contained in theburning-duid.'

The end of the pipeD is attached to a short branch pipe, H, whichextends out from one side of the trap and above the cavity I. Thiscavity, it will be seen, forms the lower part of the trap, and isprovided with the usual plug for the purpose of cleaning it out Wheneverso desired. Y

Extending directlyfrom the top ofthe cavity, and forming a solid part ofthe trap in the same IOO e j l "semola manner as the pipe H, is an.outlet-pipe, l', l ing to pass the hand through burning-vapor, which isconnected with the horizontal pipe by the hand, and in order to. preventthe plug,

1-5 from forcing it too far up, there is a hole or v socket bored vinthe top ofthe plug, as shown. The cavity is placed below the strainer,as is here shown, for the purpose of catching as much of the sedimentand lother impurities 2o contained in the-fluid as possible, so thatthey will settle from their own gravity without.

, clogging the strainer. Should any of them not settle in the cavity,the strainer will arrest them and prevent them from passing on into thepipe K. By this construction the strainer.

does not become clogged up so easily nor frequently, and thus saves timeand trouble.

The pipes K D are intended to be united rigidly together, so as to formpractically one" 3o pipe. The pipe K, instead of being held stationaryin the legs of the frame, as heretofore, is here made to partially turnor rotate for the purpose of moving the burners, so as to cause them tobe automatically extinguished when 3 5 the reservoir is moved for thepurpose of being filled. By connecting the pipes K and D together andcausing them to rotate or move in such a mann'er as to extinguish theburners before the reservoir can be lled, nothing is 4o left to thejudgment or discretion of ignorant persons thatgignoraltlyttempt to llthe, tank while the burnersY arefin operation. The object of this partof my invention is to place the operation of the burners absolutelybeyond 3 the control of' all persons who may haveto fill the tank, andthus positively prevent all danger of accidents from this source. Tothis pipe K are secured any desired number of burners, which burners,being readily secured to the pipe, are, as a matter of course, made torotate or turn with the pipe when the pipe is partially rotated, ormoved when the tank is tilted to one side, as shown in Fig. 1. v

5 5 To theneedle P is attached a suitable ca ni or equivalent device, Q,by means of which the nee 'die is given a short or quick endwisemovement for the purpose of turning on or shutting off the vapor. To theouter end of this cam or other def 6o vice Q is attached anoperating-rod, B, which is made removable from the cam, and this rod ior operating-lever then extends outward far enough to be operated bymeans of the hand,

foot, or a device of any kind. The object of this is to dispense withthe wheel which generally extends under or to one side of thefilling-cup,` and thus prevent the necessity of hav when this cupaccidentally overflows, for the purpose of shutting off the vapor. Asidefrom the danger and inconvenience of having to pass the hand through theburning-duid, the hands of the person operating the stove are frequentlyotherwise engaged, and then he or she has only to touch the rod B withthe foot, when the flow of liquid can at once be stopped. The greatadvantage of this cam, aside froln the convenience of being able toVoperate the burner without the necessity of stooping down or using thehands, consists in the short, quick, and direct motion that is given tothe needle and the ease with which the iiow of the fluid is controlled.This needle will be packed by means of asbestus or any otherimperishable or refractory substance which will not be injured by theheat. The movement ofthe needle not being necessarily greater thanone-sixteenth of an inch, it will readily be seen that the wear of thepacking is so very slight it will" last for years without allowing thevapor to leak or the necessity of being renewed.

Pivoted to the under side of the base of the burner is a cut-off orplate, S, -which has a IOO prevent the cut-off from being moved too farin either direction. When the cut-off is moved into the Vposition shownin Fig. 5, the vapor passes freely up into the burner; but when thiscut-ofi` is moved into the position shown in dotted lines in Fig. 5 thevapor will be prevented entirely from passing up into the burner,

but will be deflected by means of the cut-away portion, recess, orcavity U, which is formed in one side. This cut-away portion or cavity Uconnects at .its inner end with the hole through the cut-off, and whenthis cut-off is so moved as to entirely intercept the iiow of, vaporinto the burner, or only partially'so,

'the vapor is diminished for the `purpose of forming an auxiliaryheating-flame, for the purpose of keeping up the heat or vaporization,so as to keep the burner ready for instant use, or to keep warm anyobject or article when the main flame is not in use. This cutawayportion U deiiects this auxiliary heatingjet directly toward and againstthe top of the stand-pipe and the bottom of the burner, so as to keepthe burning-Huid'vaporized andthe burner ready for instant use.

As the burners are to be extinguished when the pipes K and D arepartially rotated, there is secured to the under side of the top of thestove, in any suitable proximity to each burner, an arm, V, of anysuitable shape'or construction that may be preferred, and against whichthe lower ends of the needles l? or the levers R, as may be preferred,are made to strike as the burner is being tilted over, and thus forceIIO 287,9ii L3 the needle upward, so as to instantly cut off the iiow ofvapor. I do not limit myself to any particular form of arm, or as towhether the needle itself or thelever connected thereto shall strikeagainst the pendent arm V, for either may be used, as preferred, theonly object being to operate'theneedle endwise, so as vto cut o thevapor and extinguish the burner before the tank is moved into such aposition that it can be iilled.

I do not limit myself to any precise construction of burner, nor to anymethod or manner of extinguishing the burner when the pipe is made topartially rotate, for this may be varied in a great many different ways,one of which is shown in Fig. 9. In this case a-short rack is formedupon an arm or pendant, which may be secured to any part of thestove-frame, and there will be a wheel provided with teeth attached-tothe lower end of the needle. As this pipe K is made to partially rotate,Ithe teeth upon the hand-wheel will be made to engage with the rack, andthus rotate the handle and close the needle. In this case the teeth uponthe hand-wheel will preferably be made in sections, with blank spacesbetween, so that after the handle has been rotated so as to shut od thevapor a blank space will be brought up to the teeth on the rack.

W'hen the burner is turned back in position after the tank has beenfilled, the backward movement of the burner causes the teeth upon thewheel to again engage with the rack and to turn on the vapor, so that bythe application. of a lighted match the burners will again light. Thistoothed wheel is intended to be turned only one-half around, all furthermotioubeing prevented by a'suitable stop. NVhen ,the burners have beenshut off by hand, the blank spaces are brought opposite the teeth on therack, and tl1en,when the pipe K is turned and the burner is tilted toone side,thefwheel does not engage with the rack, and hence the wheelsdo not engage with the rack either when the burners are being tilted orwhen they are being moved back into position. By

this constructionthe burners are again turned ot'f, if they arelighted,when the tank is being tilted for the purpose of being filled;but if the burners are closed before the tank is tilted, ,they remainclosed after it is returned to position.

W'here the' toothed hand-wheel is used, the inner end of the handle hasa small projection which acts like a crank, and which has aconnecting-rod, X, connected to it; This connectingrod is fasteneddirectlyto the lower end of the needle, so as to impart a direct endwisevmovement to it. In this case the stuffingboX for the needle can bedispensed with.

Having thus described my invention, rI claimf l. In a vapor-burner, thecombination of a tank, a pipe or pipes connected thereto, and which areadapted to move or partially rotate, one or more burners which'aremovable with Ythe pipe or pipes, and a means for automatically shutting`off the iiow of vapor from the burners, substantially as shown.

2. The combination of the tank, the vertical pipe connected thereto, thehorizontal pipe to which the burners are secured, and the frame of thestove, the two pipes being secured together,so as to form practicallyone, and adapted to move or partiallyrotate for the purpose ofautomatically extinguishing the burner or burners when the tank isturned into position to be filled, substantially as described.

3. The combination of a partially-rotating pipe, to which a burner orburners are connected, and a means for moving the pipe, the burners, andmechanism for operating the needle of each burner, so as to extinguishthe flames when the pipe is rotated, substantially as specified.

4. In a vaponburner, the trap G, having the inlet I-I, the outlet I',and the cavity I, provided with the screw-plug, and which cavity isplaced below both the inlet and outlet, in combination with theremovable strainer provided with the 'rod or handle M, substantiallyas-shown.

5. In a vaponburner, a cut-off having the recessed or cutaway portion Uin its side, for diverting the vapor and forming a subsidiary jet,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
